PHOTOGRAPHIC APPARATUS.

T0 all whom t may concern:

Be it known that I, HERMAN FAULKNER, of Salt. Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Photographic Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

This invention relates to photographic apparatus, and more particularly to means for handling and progressively feeding stereoscopic plates, photographic plates, cuts, films or photographic prints.

One object of the invention is to provide a machine of the character described which shall be adaptable for feeding plates progressively in quick succession for making or for projecting so-called moving pictures, or for exhibiting, in more or less rapid succession, photographic prints on cards.

A further obJect is to provide means whereby hotographic prints can be made successive y, and so to construct the machine that the rapidity of the feeding of the sensitized printing paper can be regulated and made dependent upon the quantity and strength of the light employed.

A further object is to construct the m( chine in such manner that it can be adapted for use in feeding various quantities and sizes of plates, films or prints.

A further object is to so construct a machine for feeding plates, films or prints, that it can be operated to convey the plates, films or prints continuously and successively from one magazine to another and back again so that they may thus be caused to travel in a continuous circuit through the magazines and be exposed or subjected to the infiuence of light during their transit from one magazine to another.

A further object is to provide a machine which may constitute an automatic photographic magazine camera Which Will operate to make both ordinary and stereoscopic pictures and also perform enlarging and reducing Work at any desired speed consistent with the strength of the light and the sensitiveness of the photographic emulsion employed.

Specification of Letters Patent.

Application filed April 16, 1909.

Patented Jan. 2,1912. serial No. 490,379.

A further object is to provide an automatic magazine feeder of slides for stereopl ticon use, which shall operate to handle such slides so as to expose them in rapid succession, and so that said slides can be made to succeed each other in fractional parts of a second intermittingly or continuously; so that panoramic lantern slides can be fed in succession continuously or intermittinglyor so that motion-picture cut-film lantern slides can be fed intermittingly in rapid succession.

A further object is to provide a machine of the character described, by means of which a multitude of mounted photographs or designs of uniform size, can be displayed continuously or intermitt-ingly at one position at any desired speed, to the fractional part of a second.

A further object is to provide a machine which shall be adaptable for use for automatically feeding mounted photographs,

post-cards and the like to a refiectoscope,`

Where the ictures or designs are enlarged, illuminated? and thrown on a screen.

A further object is to provide an automatic magazine feeder for all sorts of uniform sized material which needs to be accurately and quickly carried to fixed positions to receive the mark of other machines adjusted to do Work on said material in such fixed positions.

A further object is to so construct a machine of the character specified that it can be adjusted from front to rear to vary the capacity of the magazines; so that it can be adjusted lengthwise to adapt it for use with plates of different lengths; so that it can be adjusted from top to bottom to adapt it for plates of different heights; and so that it can be adjusted for the accommodation of plates of different thicknesses.

With these and other objects in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings Figures l and 2 are views Which, when read together, constitute a plan of a machine embodying my invention, the parts 62, 69 and 72 being broken away to afford a better view of underlying parts,-said views 1 and 2 also showing portions of the shutter frame and gearing, in dotted lines; Figs. 3 and 4 constitute a rear elevation of the machine,hthe front elevation differing therefrom only in that the driving eccentric, and parts operated thereby would appear in the reverse positions to those shown in Figs. 3 and 4.

The entire mechanism, with the exception of the lenses, and the means for applving power, is inclosed within a suitable lighttight casing` not shown.

The machine comprehends an automatic plate feeding structure comprising a frame carrying two trapezoidal magazines symmetrically placed with respect to each other; means for conveying the plates through the magazines in parallel positions, parallel to the planes of raceways; two parallel raceways at right angles to the outer ends of the magazines and serving as guides for the plates in train fashion during their travel from one magazine to the other at both front and rear of said magazines; two windows or openings, one in each raceway, at which positions are performed the various kinds of work on the plates desired; means for conveying the plates from the delivery ends of the magazines through the raceways and accurately centering them at the Windows, and means for conveying the plates from the raceways into the receiving ends of the magazines.y

The machine also comprehends the use of a photographic camera and projection shutter, and a printing frame adapter to be connected with the feeder, and also means for applying power to the various operating de vices for operating them in their proper order and time.

In constructing the framework of the machine, I employ two vertical front and rear frames each comprising a series of four uprights 55 having slotted intermediate portions; posts or uprights 67 and 68 near one end of the frame, and horizontal upper and lower longitudinal beams connecting the uprights. Each of said horizontal beams comprises three members 78-78 and 57, the latter being slotted and adjustably secured to the former. The front and rear frames are connected by extensible cross beams or braces 50, 62 and 66 as best Yshown in Figs. 1. 2, 6 and 9.' The two intermediate uprights 55 of each front and rear frame are so spaced apart that windows or openings a may be formed between them, and between the central and end uprights 55 of the respective frame, two horizontal magazines 5, are disposed transversely of the framework. and these magazines communicate at both ends with raceways c, c, through which plates are to be passed from one magazine to the other and resented, during such passage, at the windbws or openings a, as will be more fully hereinafter explained.

Each magazine is made trapezcidal in shape at each end of the inner wall with a small gate or opening. The object of the trapezoidal shape of the magazines is to provide a wider mouth at the receiving than at the delivery end, thus enabling feeding devices hereinafter described to readily move the incoming plates into the magazine well out of the path of the plates in the raccway in advance of the full sweep of the plates in this path. Such arrangement will prevent any rebounding action of the advance plate when striking against the outer magazine wall from reacting on the succeeding plate causing a check to its forward motion into the magazine from the raceway. The symmetrical arrangement of the two magazines arises from the condition that the widednouthed receiving ends ot the two magazines are located at diametrically opposite corners of the plate circuit.

The two magazines are identical in construction, and hence a detail description of one will sutlice for both.

Each magazine comprises a t'loor 3l, a top or ceiling 35, and sides 34 and 70, and each of these members is made eXtensible to vary the length of the magazine and hence accommodate the latter for the reception of different numbers of plates,-it being understood that when the machine is operated to pass plates in front of the windows o in the two raceways and to make the travel of plates to follow continuous circuit through the magazine and raceways, a sutiicient number of plates should be employed to fill both magazines so that when a plate is discharged from one end of a magazine, another plate will enter the other end of the same magazine and thus keep the same filled.

The inner wall 34 (see Figs. 30 and 31) of each magazine comprises two slotted intermeshing members, each provided at its respective ends with cross bars 38 and 131 which connect the bars of each member. One member of the side 34 is therefore, adjustable lengthwise with respect to the other member. The coperating walls of the slots ot the respective members of the side 34 are preferably beveled and lateral displacement of one member relatively to the other is prevented by means of a bar 39 secured at its respective ends to a cross bar 38 and 131 of one member 31 and passing over a cross bar 131 of the other member. A screw 33a passes through the latter and a slot 38" which extends throughout the major portion ot' the bar 39, and between the head of this screw and the bar 39, a washer 39 is located and adapted to engage said bar to clamp the members of the magazine side 34.- in any position to which it may be adjusted. The inner side wall 34 of the magazine is provided, at the delivery end of the latter, with an adjustable gate 36, the parallel arms of which are adapted to be made to project more or less into the raceway and thus afford means for determining the thickness of the work (the plates) which may be permitted to pass ont of the magazine into the raceway. The gate 3G is held at any desired adjustment by means of a set screw 37. The other or outer wall of each magazine is made extensible substantially as above described in connection with the inner Wall 34, except that the latter is somewhat shorter than the outer wall, thus allowing the work (plates) to readily pass into the magazine at the receiving end and out at the delivery end. Furthermore, the outer wall 70 is hinged at one end to form a door which enables thc charging of the plates into the magazine in the first instance, and this outer wall or door 70 is provided at its free end with a suitable latch 70a. The side Walls 31 and 70 of the magazine are adjustably supported by means ot' slotted brackets 80, which in turn are secured to the fioor and ceiling strips 81 of the raceway by means of clips 3, as clearly shown in Figs. 7 and 10. The strips 81, which extend the full length of each raceway are supported by blocks 65 and the latter in turn, are secured by the uprights 55 of the framework.

The floor 31 of each magazine is made eX- tensible longitudinally and the construction which permits such adjustment, is substantially the same as that of the magazine sides, and as shown in Figs. 32 and 33. The respcctive ends of each magazine Hoor 31, are

provided with projecting floor plates 40 having grooved under faces to receive supporting rails 77, and the latter are secured to the blocks 65,-the latter being attached to the frame uprights 55 as before explained. By this construction, an interlocking connection is aii'orded between the magazine floors and their supports. The outer edges of the projecting magazine floor plates 40 terminate in proximity to the raceway Floors and are beveled for a purpose which will hereinafter appear.

Each magazine ceiling 35 is made eXtensible in a manner similar to that of the side walls and floors of the magazines, (see Figs. 27 and 28) and the said ceilings may, if de sired, be supported by rails 77a secured to the blocks 65. However, the extensible magazine ceiling 35, shown in position in Figs. 1 and 6 and in detail in Figs. 27 and Q8, is shorter than the magazine Hoor 31 and carries at each end loose depression idler rollers 32 which operate to depress a conveyer belt 71 into frictional contact with the upper edges of plates in the magazine. The laterally projecting portions at each end of the magazine ceiling (to which the brackets for the ljournals of rollers 32 are secured) have adjustably secured thereto, slotted L- shaped clips 33. The clips 33 at each end of the ceiling 35 can be adjusted horizontally (by loosening the set screws) and the vertical members of these clips, projecting downwardly, make frictional contact with arms 36 (Fig. 6) secured to bars 38 of the magazine side walls. The depending members of the clips 33 are also connected with the arms 36 by means of coiled springs 86a. Thus, the magazine ceiling is supported so as to be capable of slight vertical play, the springs 36 permitting such movement to cause an equalization of the belt 71 on all the plates in the magazine, although some of said plates may vary slightly in their vertical dimensions.

As shown in Fig. 6, the conveyer belt 71, passes under the magazine ceiling 35, and a similar belt 7la passes over the magazine Hoor 31. These belts will be so driven (by means hereinafter' explained) that their horizontal portions will travel in the same direction and operate, by engagement with the plates in the magazine, to move the same forwardly through the latter toward the respective raceways.

The upper conveyor belt passes over rollers T3 and 7 6 having their journals mounted in blocks 65 over the respective ends of the magazine. This belt also passes over idle rollers 'Z4- 74 disposed between the rollers f3-76 and having their journals mounted in brackets 74 adjustably secured to and depending from the slotted transverse beams 6G. It is apparent that by adjusting the brackets 74*l on the beams 66, the belt 71 may be tightened or loosened as may be necessary to effect the effectual feeding of the plates. In a similar manner, the lower feed or conveycr belt 7la which passes over the magazine floor 31, also passes over rollers 73 and 76'* havin their journals mounted in the lower blocs 65 below the ends of the magazine. This lower belt 71*l also passes over idle rollers Mb- 74h having their journals mounted in brackets 74 adjustably secured to the lower slotted rails 66. It is apparent that the lower feed or conveyer belt may be tightened or loosened by adjusting one or both of the brackets 74". It will be observed that the lower belt 7l passes over the beveled outer edges of the Hoor extension plates 40. These beveled portions of the plates 40 afford smooth surfaces for the passage of the belt as it passes from over the magazine floor to the rollers below the latter. The beveled ends of the floor plates 40 are in proximity to the raceway Hoor strips 81, the adjacent edges of which latter are beveled as shown in Fi 6. Thus elongated slots 81a are forme through which the lower belt passes out of or into the magazine. If desired the belt roller of each set to which power is applied may be sanded to prevent slipping.

As hereinbefore explained, the plates are fed in vertical position, from a magazine to one of the raceways, and that the strips 8l constitute the ceiling and floors of said raceways. The outer wall of each raceway 1s formed by blades 64 which are adjustably attached to the uprights of the frame work, and these raceway blades, extending past the mouths of the magazines, constitute end walls for the latter. The plates are fed from the magazines to the raceways and made to bear against the outer wall,or blades 64: of the raceway, said plates being then moved forwardly through the racewa successively by means of devices yet to e described. The inner wall of each raceway comprises three members 89-89-96 (Fig. 8) extending only between the inner magazine walls. The two parts 89-89 are slotted and can be drawn apart to increase the eii'ective length of the inner blade or member 96 were the inner magazine walls to be drawn apart. No screws are passed into or through the raceway floors or ceilings 81 as they are held in position by the blocks 65 (Fig. 6) and the clips 3 (Figs. 7, 8 and 10) as before explained. Clips 3 also serve to secure the inner raceway blades 96 to the floors and ceilings 81 in such manner as to allow the inner blades 96 and 89 to be adjusted with respect to the front or outer4 blades 64 so as to afford a shallower or deeper raceway and thus enable the machine to be used at diferent times in carrying various thickness of work.

It has been hereinbefore explained that the plates are fed from a magazine to a raceway, and the mechanism will now be described by means of which the plates are moved successively through a raceway, exposed at a window a therein, and then moved to the receiving end of the other magazine, to be discharged therein, conveyed therethrough and then passed through the other raceway, exposed at the window a therein and finally returned to the receiving end of the first magazine.

For moving the plates forwardly in the raceways as said plates enter the latter from a magazine, I employ reciprocating shuttles 90-91 adapted to engage, alternately, the rear edges of the plates only long enough for each rear edge to move slightly beyond the inner face of the inner wall of the magazine,-the plate being impelled the remaining distance through the raceway to the receiving end of the other magazine by the advancing edge of the next succeeding plate, and the latter is impelled by the other shuttle. The machine would be operative to feed plates through the raceway, with the use of one instead of two shuttles, but the speed of the feed and the speed of successive exposures of the plates at the window a would be reduced. The mechanism at both front and rear of the machine is the same, thus rendering a detail description of both unnecessary, and as the plates are discharged from one end and received by the other end of each magazine, the connections for operating the devices which cause the passage of the plates through the raceways will be such that the action of the shuttles 90 and 91 will be exactly the same at the delivery end of both magazines and at the same time, corresponding shuttles 90 at diagonally opposite corners of the plate circuit (see Figs. 1 and 2) each carrying a plate into its raceway. When the machine is in operation, an odd number of plates (three when adjusted as shown in the drawings) will be in each of the raceways. The sweep of the shuttles 90 and 91 (Fig. 3) are the same, and are just right, with the aid of the alinement of the plates of uniform length to properly center at the operating window a., the middle plate of the series in the raceway.

Strips or guides 1G having beveled edges (Fig. 2l) are provided for the accommodation of the shuttles 90-91 and these strips or guides are attached to standards 55 of the framework in a manner to permit their vertical adjustment. Each shuttle 90-91 comH prises two members adjustably connected together and provided with bearing blocks 26 having grooves in their inner faces for the accommodation of the guides 16. By adjusting the members of the shuttle relatively to each other and correspondingly adjusting the guides 1G, the shuttle may be adapted for use with plates of different heights. Arms or links 52 are pivotally attached to the bearing blocks 2G of the shuttle and to these arms or links a shuttle plate 19 is adjustably attached as shown in Figs. 20 to 23. The shuttle plate 19 is provided with arms 24 having holes for the free passage of headed pins 24", said pins being adjustably secured to arms 24c projecting from one of the shuttle members and having springs 24c1 thereon, interposed between said arms 24i and 24, and the whole constituting governors 24. By the action of these governors, pawls 17 (or a pawl plate 18 if the same be employed in conjunction with or in lieu of the pawls 17) adjustably attached to the shuttle plate, will be quickly thrown back into the delivery portion of a magazine (if previously thrown out from any cause) at the proper time to engage the rear edge of a plate. The pawl governors 24 can be adjusted to allow the pawls 17 or pawl plate 18 to extend into a magazine just the correct distance to carry out at one time, the amount of work desired, Whether one or more plates. The shuttle plate is slotted to permit of adjustment of the shuttle for plates of diil'erent heights as before mentioned. The pawls 17 can likewise be adjusted until they will engage the rear edges of the plate at or near the upper and lower edges of the late. In moving delicate plates by means o the shuttles, it is desirable that neither the pawls 17 nor the pawl plate 18 shall be in contact, on the return stroke of the shuttle, with the succeeding plate, after delivering a late into the raceway. To accomplish this, I provide parallel lift rails 25 (see Figs. 11 and 20 to 22) adjustable longitudinally with relation to each other and supported between the shuttle guides 16, by means of rails 27 secured to standards 55 of the framework, and said lift rails are provided (each at one end) with a cam face 25a (see Fig. 20). The transverse movable plate 19 of the shuttle, which carries the plate-engaging pawls, is provided with an arm 20, to the free end of which a bracket 21 (carrying a roller 21) is pivotally supported in such manner that when the shuttle moves forwardly to propel a plate in the raceway, said bracket will turn on its fulcrum and permit the roller 21a to ride up one of the cams 25 of one of the lift rails without moving the arm 20 or the shuttle plate 19. When the shuttle starts the return movement toward the delivery end of the magazine, the roller 21"l will ride on the cam end of the other lift rail without turning the bracket 21 in which said roller is mounted (the bracket being so pivoted as to be locked against turning when the shuttle is making its return throw) and hence the arm 2() will be moved so as to shift the shuttle plate 19 (the latter being pivotally supported by means of the links 52) and move the plate-engaging pawls out of line with the plates in the raceway, and thus said paWls will be prevented from engaging the incoming plate in the raceway when the shuttle is making its return stroke. The bracket 21 is normally retained in position by means of a flat spring 22.

Near one end of the framework a shaft comprising members or sections (S0-61 is mounted in adjustable brackets 54 and provided with a gear wheel 42 which receives motion from a gear wheel 41, the latter bein driven by means of a hand-crank or any suitable motor not shown. Power for operating the various moving elements of the machine is derived from the shaft (iO-61. The members composing this shaft are telescopic to permit the shaft to be lengthened when the frame is distended and the magazines lengthened as previously explained.

Eccentrics 51 are secured to the shaft 60-61 near respective ends thereof and are disposed reversely to each other so that they will be made to operate the shuttles at the front of the machine in the reverse order to the operation of the shuttles at the rear of the machine, by means of the various connections presently to be explained. With the exception of this reverse order of operation, the operating mechanism for the devices for moving plates from one magazine and depositing them into the other, is the same at the front and hence a detail description of one will suffice for both. In Figs. 3 and 4 of the drawings, the rear side of the machine is represented. An eccentric cross head 51 is provided for eccentric 51a and has a slotted arm 53 for the reception of an adjustable fulcrum which pivotally connects said arm With the slotted lower portion of a walking beam 79,--the latter being pivotally supported between its ends by a suitable pin adjustably supported in the intermediate slotted portion of a standard 67 secured to the framework. The Walking beam is slot-
